Abstract

This study addressed the effect of scaling subjects in a virtual reality environment when performing ergonomic evaluations for assembly automotive tasks. Ten male and ten female automotive employees participated in this study. Subjects were selected to fit into one of 4 anthropometric groups (n=5/group); 5th percentile female (5F), 50th percentile female (50F), 50th percentile male (50M), or 95th percentile male (95M). Each subject was asked to perform 3 automotive assembly tasks while interacting with a digital rendering of a vehicle in virtual reality. The subjects were represented in virtual reality as a human manikin (Classic Jack, UGS) whose actions were driven by their actual motions captured via motion tracking (EvaRT, MotionAnalysis). Each subject performed the tasks under 4 different conditions; in one condition, the subject appeared as their true size, and in the three other conditions, they were scaled to appear as the size of the other three subject groups.
